Handling
The product can be applied by Mayer-bar, knife-coating, reverse-roll, etc., If necessary, it can be diluted with water or thickened with polyacrylic thickeners.
The quantity to be applied depends on the substrate and may vary from 1 to 3 g dry/sqm. In general, 1,5 g dry/sqm is considered optimal.
In order to obtain the highest releasing properties, we recommend to heat the product at 150°C for a few seconds. A self-curing process is triggered after the drying. Ageing properties are excellent.
